What is Fibratus?

Fibratus is a tool for exploration and tracing of the Windows kernel. It lets you trap system-wide events such as process life-cycle, file system I/O, registry modifications or network requests among many other observability signals. In a nutshell, Fibratus allows for gaining deep operational visibility into the Windows kernel but also processes running on top of it. It requires no drivers nor third-party software.

Events can be shipped to a wide array of output sinks or dumped to capture files for local inspection and forensics analysis. The powerful filtering engine permits drilling into the event flux entrails and the rules engine is capable of detecting stealthy adversary attacks and sophisticated threats.

You can use filaments to extend Fibratus with your own arsenal of tools and so leverage the power of the Python ecosystem

Quick start

Check the walkthrough on how to load and create detection rules.

Observe Microsoft Outlook attachments creating on the file system

fibratus run file.operation = 'create' and file.name icontains '\\Content.Outlook\\'

Hunt remote thread creations

fibratus run kevt.name = 'CreateThread' and kevt.pid != thread.pid

Record network interactions to the capture file

fibratus capture kevt.category = 'net' -o conns.kcap

Replay events from the capture

fibratus replay net.dport in (443, 80) -k conns.kcap

Run the filament for watching file system changes

fibratus run -f watch_files
